Answer:E = hc/? = 4.41 x 10-19 J
Energy absorbed by each atom :
E (atom) = 2.205 x 10-19 J
Now Bond Energy of each molecule (B) = 3.98 x J
So, for each atom 1.99 x 10-19 J
So now
KE of each atom = E(atom) - B (atom)
= 2.15 x 10-19 J
The Pearson correlation of r can be regarded as significant or not depending on the value of alpha or the significance threshold and the number of participants. For alpha of 0.05 and the 20 samples, the significant value of r is 0.38. For alpha of 0.01, significant value of r is 0.52. From this, we can say that only at alpha of 0.05 is the correlation significant.
At first it will melt and at 100degree Celsius it will boil and start to vaporize
